https://verkehr.autobahn.de/o/autobahn/details/warning/{warning.identifier}
gives details of a warnings (list of warnings, see here)

Local stored JSON: http://api.json-content-importer.com/extra/json/nZpel9fTE1TLU5JL3JfTE1TLU5JLzI0MDQ5M19EICBOSSBMTVMtTkkgIC4w.json

JCI-Template:

• name: detail-autobahn
• URL:
  “dummyrequest” does not do a http-request but gives basic info about the page. With that you can catch errors etc.

{% set url = "dummyrequest" %}
{% if urlparam.warningid %}
{% set url = "https://verkehr.autobahn.de/o/autobahn/details/warning/" ~ urlparam.warningid %}
{% endif %}
{{url}}

• urlparam4twig: warningid
• twig-template:

<a href="/api-verkehr-autobahn-de-o/">back to list</a><hr>
{% if subtitle %}
    <strong>{{subtitle}}</strong><br>
    {{description.0}}<br>
    coordinates: {{coordinate.lat}},{{coordinate.long}}<br>
    {% for k,v in description %}
        {% if v %}
            {{v}}<br>
        {% endif %}
    {% endfor %}
{% else %}
no warning found
{% endif %}

Shortcode:

[jsoncontentimporterpro nameoftemplate="detail-autobahn"]

In Action:

Challenge:
Show current and forecast weather data via
https://api.openweathermap.org/data/2.5/onecall?lat={{lat}}&lon={{lon}}&exclude={part}&appid=….
for a searchable location.

Solution:
Use the above API for the weather at a location defined by lat and lon. Also use the openweather-geocoding API to transform a locationname into lat & lon.

In Action:

See how this is done with a JCI-Shortcode:

[jsoncontentimporterpro nameoftemplate="openweather-forecast"]

With this JCI-template:

• urlparam4twig: su
• URL:

{% set su = "augsburg" %}{% if urlparam.su %}{% set su = urlparam.su %}{% endif %}
http://api.openweathermap.org/geo/1.0/direct?q={{su}}&limit=10&appid=...

• twig-template:
  For the weather-forecast each location points at /openweather-forecast/

{% set su = "augsburg" %}{% if urlparam.su %}{% set su = urlparam.su %}{% endif %}
<form action=".">
    <input type=text name=su placeholder="Insert name of a location" value="{{su}}">
    <input type=submit value="Search location and weather">
</form>
<hr>
{% for l in _context %}
    {% if l.lat %}
        {{l.name}} ({{l.country}}
        {% if l.state %}
            , {{l.state}}
        {% endif %})
        <a href="https://www.google.com/maps/place//@{{l.lat}},{{l.lon}},14z" target="_blank">show on map</a>
        |
        <a href="/openweather-forecast/?lat={{l.lat}}&lon={{l.lon}}&su={{l.name|e|url_encode}}">show weather</a>
        <br>
    {% endif %}
{% endfor %}
